Chapter Summary
In Chapter 36, the Arctic's summer sea ice melts away completely in 2032. The thin ice that forms the next winter melts quickly in spring, which sets off a dangerous feedback loop. With less white ice to reflect sunlight, the dark ocean absorbs more heat, and the ice gets thinner. Robinson warns that this could also thaw the permafrost around the Arctic, releasing huge amounts of carbon and methane, which can push the Earth past a point of no return. To fight back, people have been trying ways to thicken the winter ice. The first is using robots that spray seawater on the ice's edge, battery-powered airships that pump water onto the ice from above, and millions of small solar powered machines that drill and spray the ice themselves. However, the projects are expensive and even burn some carbon, but they go ahead anyway because losing the ice would be far worse. In the end, none of the methods work very well, and Robinson admits that the whole effort is "awkward as hell." I think in this chapter, it shows that climate mitigation is rarely clean or heroic. Instead, a lot of the times, it is clumsy, costly, and partly effective, and it can even add to the problem it's trying to solve. However, what I think Robinson here is suggesting is that this messy and imperfect work is still worth doing because in a crisis this severe, doing something flawd is better than doing nothing at all.
How does this chapter function throughout the entire arc of the novel?
I think that in Chapter 36, it shows the novel's turn from understanding the crisis to actually fighting it, and it doesn't hide the truth about how hard it is. Earlier in the book, we see that the main threats are human, but now, we see the planet's own feedback loops start doing the damage, which raises the stakes for everything that follows. This chapter also connects to the Ministry's purpose, which is to speak for future generations. I think Chapter 36 connects very well with both Chapters 24 and 28 because Chapter 24 explains why people couldn't feel the danger until it arrived, Chapter 28 says that change depends on ordinary people acting at the right moment, and Chapter 36 shows that action actually looks slow, imperfect, and awkward, but necessary because every good work has to start somewhere.
36
The Arctic Ocean's ice cover melted entirely away in the late summer of 2032, and the winter sea ice that formed in the following winter less than a meter thick, and broken up by winds and currents into jumbled islands of pancake ice, separated by skim ice or brash ice or even open leads and internal ice-bordered seas many kilometers wide, so that when spring came and the sun hit, that winter's skimpy ice quickly melted and the constant summer sunlight penetrated deep into the Arctic waters, which it warmed quite a bit, which thus thinned the next winter's ice even more.
This was a feedback loop with teeth. The Arctic ice cap, which at its thickest measurement in the 1950s was more than ten meters thick, had been a big part of the Earth's albedo; during northern summers it had reflected as much as two or three percent of the sun's incoming insolation back into space. Now that light was instead spearing into the ocean and heating it. And for reasons not fully understood, the Arctic and the Antarctic were already the most rapidly warming places on Earth. This meant also the permafrost ringing the Arctic in Siberia and Alaska and Canada and Greenland and Scandinavia was melting faster and faster; which meant the release of a great deal of permafrost carbon, and also methane, a greenhouse gas twenty times stronger than CO2 in its ability to trap heat in the atmosphere. Arctic permafrost contained as much stored methane as all the Earth's cattle would create and emit over six centuries, and this giant burp, if released, would almost certainly push Earth over an irreversible tipping point into jungle planet mode, completely ice-free, at which point sea level would be 110 meters higher than at present, and global average temperatures at least 5 or 6 degrees Celsius higher and probably more, rendering great stretches of the Earth uninhabitable by humans. At that point, civilization would be over. Some remainder of humanity might adapt to the new biosphere, but they would be a post-traumatic remnant in a post-mass-extinction world.
That being the case, efforts were being made to thicken the Arctic sea ice in winter, which would allow it to hold on longer through the summers.
These efforts were awkward at best. Arctic winters were still sunless and cold, and a skim of ice covered most of the sea. And there was no good and obvious method to thicken that ice. So to begin with, a number of methods were tried and evaluated. One involved running autonomous amphibious craft over the outer edge of the winter sea ice as soon as it formed, each craft pumping up seawater from the still liquid ocean nearby, then spraying it into the air in a fine spray that would freeze before it came down, this flocking making thicker the outermost border of the sea ice, and hopefully thus slowing its breakup when the sun arrived in spring.
This worked, in a limited way, but it would take thousands of such vehicles to adequately thicken the sea ice, and each vehicle could only be created at the expense of a certain amount of carbon burned into the atmosphere. Nevertheless it was felt worth doing, despite the expense in money, materials, and carbon burn associated with construction of the amphibians. Now that the cost of losing the sea ice was clearly seen to be hugely more important than the financial cost of preventing the loss, the financial cost was no longer a stopper to this plan proceeding.
Then, as airship factories were proliferating all around the world, it was possible to make some that would fly over the Arctic sea ice every winter, powered by batteries, pumping up water from holes punched in the thinnest sea ice, to fill tanks and then spray that water onto the surface ice below, where it also froze and fell as flocking, and thus thickened the ice. As in the Antarctic pumping efforts, it felt at first like sucking the ocean through a drinking straw: minuscule efforts! Teensy effects! A sick little joke! But every good work has to begin somewhere. And really, if these projects didn't succeed, what would follow was so dire to contemplate that the efforts were judged worth making, minuscule or not.
The third method was to drop on the winter ice clouds of small plastic machines, each of which had a solar panel and a drill and a pump and a little sprayer, so that the machine could puncture the ice, draw up some water, and cast it into the air to freeze. Eventually these machines would get buried in snow by way of their own efforts, and then they would shut down and wait for spring and summer to come, when they would float to the surface, if enough snow melted, and wait to be refrozen into the top of the ice the following fall, where they could start all over again. Thousands and even millions of these could be distributed. If their work went well enough, they would eventually stay trapped in the thickening sea ice for centuries to come - they were even small bits of carbon sequestration, as pointed out in little attempts at a joke.
But still, it was awkward, very awkward. Awkward as hell. Nothing they tried in this effort worked very well. Which meant . . .

Robinson opens the chapter with a prediction that the Arctic's summer ice will melt entirely away by 2032. When the novel came out in 2020, this prediction may have sounded like it came from science fiction, but today, it looks more like a forecast (first image above that shows the sea ice concentration. Scientists consider the Arctic "ice free" once sea ice falls below one million square kilometers, not zero because the oldest, thickest ice will likely cling to the northern coasts of Greenland and Canada even after the rest is gone. Additionally, recent research supports Robinson's timelone is within reach. Ice-free Septembers could arrive in the 2030s if emissions stay high, and no later than the 2050s even if they are cut. Some models suggest a single ice-free day could come as early as 2027. However, scientists and Robinson look at this moment very differently. Researchers point out that the first ice-free day will not change much on its own, and that it is more of a symbolic milestone. Robinson treats it like a disaster because once the white ice disappears, the dark ocean absorbs more heat, which tings the next winter's ice and speeds up the thawing of permafrost. Honestly, I think both sides are right, just about different things because the researchers point out that the first ice-free day won't change much on its own and is more of a symbolic milestone. But, Robinson treats this like a disaster that the trend feeds itself because less ice means more heat, which means even less ice, so the problem speeds up the longer it goes.
"pancake ice...skim ice or brash ice...open leads": https://nsidc.org/learn/cryosphere-glossary/pancake-ice; https://www.meereisportal.de/en/glossary/Pancake%20ice; https://nsidc.org/sea-ice-today
Robinson describes the Arctic's new winter ice as "jumbled islands of pancake ice, separated by skim ice or brash ice or even open leads." Pancake iceis young ice that forms when waves churn slushy surface water into round plates, usually less than four inches thick and anywhere from about a foot to ten feet across. The constant bumping gives each piece a raised rim, which is why they look like pancakes. Skim ice is a thin, fragile film of new ice on calm water, and brash ice is a rubble of small broken fragments and leads are cracks or channels of open water running between sheets of ice. And actually, for the feasibility of this, there is a UK startup called Real Ice working with the University of Cambridge Bay in Nunavut, Canada. Real Ice estimates that treating about 386,000 sqaure miles would cost $5 to $6 billion a year, but many scientists still remain doubtful about that. There was also a different project, which spread tiny glass beads on the ice to reflect sunlight, but it was shut down after tests suggested it could threaten the Arctic food chain (these are very interesting to look up and research, because I didn't realize there were so many different active methods that are currently being tested). Even Desch admits that his idea is a band aid, not a solution, which I think is why Robinson calls the whole effort "awkward as hell."
"This was a feedback loop with teeth...albedo": https://www.uef.fi/en/article/warming-in-the-arctic-region-has-been-four-times-faster-than-the-global-average; https://whyy.org/npr-story/arctic-global-warming-climate-change/; https://en.wikipedia.org/wiki/Ice–albedo_feedback
The key idea here is the albedo, which is a measure to how much sunlight a surface reflects. Bright snow-covered sea ice reflects msot of the sunlight that hits it while dark open ocean absorbs more than ninety percent, so for example, it's like wearing a white t-shirt versus a black one on a hot summer day. The white t-shirt bounces the heat away, while the black one absorbs it. The newly exposed water absorbs more heat, which warms up the ocean and melts more ice. This exposes even more water. Each turn of the loop makes the next one stronger, which is what gives it "teeth." Additionally, Robinson describes that the Arctic was warming fastest "for reasons not fully understood." Scientists call this Arctic amplification, and recent research supports that it is even more extreme than once believed. For years, the Arctic was described as warming about twice as fast as the rest of the planet, but new analysis of satelittle era data show it has warmed nearly four times faster since 1979, with some areas near Norway and Russia warming as much as seven times faster. This is important because the ice loss doesn't just stay in the Arctic. Robinson connects the thawing permafrost, showing how one feedback loop can feed into another until the whole planet is affected. An interesting connection I want to make her is that the albedo loop kind of reminds me of compound interest. In finance, compounding is good when it's growing your savings, but it's bad when it's growing your debt, because every year's interest gets added to the balance and makes the next year worse. I think melting ice works the same way here because each summer's loss makes the next one bigger, and like debt, the longer you wait to deal with it, the harder it gets to pay down.
the permafrost "giant burp" and "jungle planet mode": https://www.npr.org/sections/goatsandsoda/2018/01/24/575220206/is-there-a-ticking-time-bomb-under-the-arctic; https://www.epa.gov/ghgemissions/understanding-global-warming-potentials; https://www.usgs.gov/faqs/how-would-sea-level-change-if-all-glaciers-melted; https://www.pnas.org/doi/10.1073/pnas.1810141115
Permafrost is ground that has stayed frozen for thousands of years, locking in the remains of ancient planets and animals. When it thaws, microbes wake up and begin breaking that material down, and they then release carbon dioxide and methane into the atmosphere. The scale of this is enormous because permafrost holds twice as much carbon as the entire atmosphere, which is more than all the carbon humans have emitted since the Industrial Revolution. Robinson uses "giant burp" to describe what scientists fear the most which is once thawing begins, the released gases cause more warming, which causes more thawing (a loop that humans would have very little ability to stop). He also uses the phrase "jungle planet mode." This talks about the scientific concept also called "Hothouse Earth." In 2018, a group of climate scientists warned that feedbacks like melting ice and thawing permafrost could push the planet past a threshold after which warming would keep going even if humans cut their emissions. However, some of the numbers referenced by Robinson don't match the current science (this was published in 2020). He calls methane (twenty times stronger than CO2," but today's estimates put it closer to 27 to 30 times stronger over a century, and mroe than 80 times stronger over twenty years. I also think the word "burp" is worth questioning here because it makes the release sound sudden (like one big event), and actually, most scientists expect permafrost to release its carbon more gradually over decades and centuries. To me, I think that's scarier because a sudden burp would be impossible to ignore and might force the world to act.
"the cost of losing the sea ice was clearly seen to be hugely more important than the financial cost": https://www.bu.edu/eci/files/2019/06/SternDebateReport.pdf; https://archive-yaleglobal.yale.edu/content/debating-price-global-warming; https://en.wikipedia.org/wiki/Stern_Review
This statement is also known as the cost-benefit analysis, which is a similar reasoning that businesses and governments use to decide whether a project is worth funding. For decades, climate action failed that test, and that is not because the damage was small, but because it seemed too far away. The real world version of this debate happened in 2006 when economist Nicolas Stern produced a report for the British government. Stern estimated that acting on climate change would cost about one percent of global GDP per year, while doing nothing could cost five to twenty percent. Critics like William Nordhaus argued that Stern reached this conclusion by using an unusually low discount rate, where he weighed future generations almost equally with our own. With a higher rate, the case for urgent action shrank a lot, so the entire fight came down to how much the future should count. So, once the ice is actually gone, the damage is no longer a distant estimate to be discounted, but instead, it is happening now and the numbers stop mattering. As a business major, I use discount rates all the time, and they make sense for money. But I'm not convinced the same logic works for things like ice sheets or people's lives. You can't put the Arctic in a savings account and earn interest on it because once it's gone, it's gone. What bothers me about the Stern-Nordhaus debate is that picking a discount rate looks like a technical math choice, but it's really a moral one ( I went into depth on this in Essay 1). Also, the phrase "clearly seen" is important because it suggests that people never lacked the information to act, they lacked the ability to feel the danger.
"A sick little joke!" and "Awkward as hell"
Halfway through Chapter 36, the tone changes. When Robinson starts talking about the airships pumping water onto the ice, the voice suddenly gets frusturated. By the end, Robinson just says it was "awkward as hell" and the chapter trails off with "Which meant..." as if he was too tired to finish. I think the tone of this chapter almost goes to show how Robinson sees the future. Saving the Arctic isn't heroic or exciting, and the machines are slow and awkward (they barely help). Still, he says that "every good work has to begin somewhere," and the work keeps going. I think that whole idea kind of sums up the whole novel where Robinson's better future doesn't arrive all at once, but is slowly built through lots of small and imperfect efforts. I think the humor in a way keeps the chapter from feeling hopeless and shows that sometimes you just have to laugh and keep going (me in life).
